SPECIFICATION forming part of Letters Patent No. 621,621, dated March 21, 1899.

Application filed October 20, 1898. Serial No. 694|089. (No model.)

To all whom it may concern:

Be it known that I, CHARLES SEYMOUR, of Defiance, in the county of Defiance and State of Ohio, have invented a new and Improved Shaping-Machine, of which the following is a full, clear, and exact description.

The invention relates to Woodworking machinery; andits object is to provide a new and improved .shaping-machine more especially designed for automatically and properly shaping or rounding the inside portion of the handhold or grip of the D-handles used on shovels, spades, forks, and other implements.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a perspective view of the improvement. Fig. 2 is a plan view of the same. Fig. 3 is a sectional side elevation of the same on the line 3 3 in Fig. 2. Fig. 4 is a perspective view of the handle previous to finishing the inside portion of the handhold or grip, and Fig. 5 is a like view of the finished handle.

The improved machine is mounted on a suitably-constructed frame A, formed with a vertically-disposed socket B, in which is mounted to turn the shaft C of a table O, adapted to support the handle D to be operated on, saidl handle resting with its shank on a fork E, carried near one outer end of the table, as is plainly shown in the drawings. The end D of the handle D is adapted to be engaged at opposite sides by jaws F, fulcrumed at F on the top of the table O and carrying at their outer ends friction-rollers F2, adapted to be engaged by a wedge G, projecting from a lever G', to swing the wedge inward and move the outer endsof the jaws outward and the clamping ends inward, to securely engage and clamp the sides of the handle end Dl and hold the handle in position on the top of the table O while undergoing treatment.

The lever G is fulcrumed on a horizontallydisposed stud G2, mounted to swing on a ver tically-disposed stud Ga projecting from the table C, to permit the operator to move the is adapted to be fastened in place on the stud by a set-screw H?. The handle H serves to give the operator a grip when engaging the free end of the lever G to swing the lever inward and close the jawsF by the action of the wedge G on the friction-rollers, as above explained.

The inside of the grip or handhold D2 of the handle D is square, as shown in Fig. 4, and said square portion is rounded to permit convenient gripping by the operator of the implement on which the handle D is used. In order to round the grip or handhold on the inside, I employ a knife I, secured by bolts J to the under side of a knife-carrier K,mounted to swing in bearingsK, formed on the frame A, the transverse axis of the bearings coinciding approximately with the axis of the grip or handhold D2, as will be readily understood by reference to Fig. 3. Thus when the carrier K receives a reciprocating motion' at the time the handle D is secured in position on the table C then the knife I will cut the grip or handhold D2 on the inside thereof to give the grip the desired shape. The oscillating motion given to the carrier K and the knife I corresponds to about a quarterturn,so that one-half of theinner portion of the grip or hold is cut at a stroke of the knife, the table O being turned after completion of the stroke to bring an uncut portion in alinement with the knife, so as to be cut at the next stroke. This operation is repeated until the grip or handhold has been cut throughout its length from one side of the handle end D to the other, it being immaterial from which side the cutting is started. When one side of the handle-grip has thus been nished, the handle is released by swinging the lever G outward, and then said handle is turned over and the described operation is repeated-that is, the handle is clamped in place and the knife I on reciprocating cuts the remaining quarter part of the inner portion of the grip or hold.

In placing the handle in position `on the IOO table the handle end D is placed upon the surface of the table, the opening in the handle end being over an elongated opening C2 in the table C, the shank of the handle resting in the fork E. The chips out by the knife I from the grip or hold D2 drop through the registering openings mentioned to the floor.

In order to give the desired oscillating motion to the carrier K, I pivotally connect the same by a pitman L with a crank-disk N, secured on a shaft O,mounted to turn in suitable bearings carried by the frame A. A suitable friction driving pulley P, connected with other machinery, serves to impart a rotary motion to the shaft 0 and the crankwlisk N to cause the pitman L to impart the desired swinging motion to the carrier K and the knife I. It is understood that after cach oscillation of the knife the operator turns the table C with the hand not engaged in holding the lever G', for the purpose mentioned.

In order to prevent the knife I from cutting into the sides of the handle end D', I provide the peripheral surface of the table C with a lug C3, adapted to abut against stop-pins Q, when the knife reaches either sideof the handle end. The stops Q are in the form of screws to permit of limiting the turning motion of the table C, according to the length of the inner portion of the grip to be treated. The knife I is preferably provided at its side edges with flanges, as plainly shown in Figs. 2 and 3, to prevent the knife from accidentally cutting into the sides of the handle end D.

' By the use of this machine the inner portion of the grip or hold of the handle is nished to perfection without requiring skilled workmen.

The machine is simple and durable in construction, is not liable to get out of order, and

permits of shaping a large number of handles in a comparatively short time.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a shaping-machine, the combination of a table, two jaws mounted thereon and adapted to clamp the work, and a lever located above the table and mounted to swing vertically and horizontally, the lever having a wedge adapted to enter between the clamping-jaws to force the same against the work, whereby the work may be laid on the table and held by the clamping-jaws, and whereby the lever may be pressed down on the work, to force the same against the table.

2. In a shaping-machine, the combination with a table, of clamping-jaws mounted thereon, a lever located above the table and mounted to swing in the plane of the table and perpendicularly thereto, and having a wedge entering between the clamping jaws, to force the same into action, and a handle fast to the table and adjacent to the free end of the leverand serving as a hand-grasp, to assist in the manipulation of the lever.

CHARLES SEYMOUR.
